Abstract

1438422 Cephalosporin derivatives AP DA LUZ 27 March 1974 [2 July 1973] 13705/74 Heading C2C Novel compounds I (R<SP>1</SP> is an organic radical other than 4-amino-4- carboxy-n-butyl; R<SP>2</SP> is an organic radical different from R<SP>1</SP>; R<SP>3</SP> is carboxyl or protected carboxyl; X is H, OH or an organic radical) are prepared by acylation of a compound IV The compounds I may be selectively deacylated to give compounds II
